CLAMP.

Application filed. March 17, 1923.

This invention relates more particularly to a classof holding devices.

My invention has for its object primarily to provide a device or clamp designed to be D employed for various purposes, such as securely holding in contact or in close juxtaposition a number of articles, and which is of a form mainly adapted for use in the manufacture of shoes and like footwear for persons whereby the work of mounting heels on the footwear may be greatly facilitater, especially when the heels are of forms which when mounted on the uppers of shoes require normal positions on inclines varying from a vertical line corresponding with the center of the heel portion of the upper, thereby overcoming the requirement for using wedges to even the irregular planes of the parts engaged by the clamp as is incident to present methods. The invention resides mainly in the provision of a jaw member having a flat head which is pivoted to one end of a substantially C-shaped spanning frame whereby the head may be adjusted to inclined positions from a normal position in spaced opposed relation to the other end of the frame so that the adjustable jaw member will properly engage the thread end of the heel when the device is used for clamping the heel and upper of a shoe together, in order to avoid the employment of wedges.

A. further object of the invention is to provide a clamp of a simple, efficient and durable construction which may be made of suitable material in any appropriate size and shape.

With these and other objects in view, the

invention will be hereinafter more fully described with reference to the accompanying l drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end of the description.

In the drawing, Figure 1 is a fragmentary view showing the manner of using the device for clamping the heel. and upper of a shoe together.

Fig. 2 is a side elevation of the device.

59 Fig. 3 is an enlarged fragmentary view showing parts of the device taken on the line 3-3 of Fig. 1, and

Fig. 4 is an enlarged detail sectional view taken on the line 1 1 of Fig. 1.

55 The device or clamp has a spanning frame 10 of preferably somewhat a C-shape to Serial No. 625,823.

provide a body portion or bar 11 having its end portion bent angularly whereby two spaced extension members or arms 12, 13 are provided so that the arms are on alinement with their ends in opposed relation. By making the spanning frame of this form and when of an appropriate size two or more articles, such as the heel portion of the upper, as 1 1, and the heel, as 15, of a shoe, as 16, may be freely accommodated between the ends or arms 12, 13 of the spanning frame.

The end of the upper arm 13 of the spanning frame terminates with an interiorly threaded sleeve 17' the passage of which is in register with the free end of the lower arm 12 of the frame. In the passage of the sleeve 17 is screwed a threaded stem or bolt 18 which is longer than the length of the sleeve, and on the upper end of the stem is a fixed wing nut or head 19 for being gripped by a person so that the stem or bolt may be rotat ably adjusted toward and from the arm 12 of the "frame 10. On the lower end of the stem 18 is a jaw member 20 having a flat head or plate 21 which is mounted to the stem by means of a ball and socket universal joint, as 22, to allow the jaw member to be adjusted whereby its flat head 21 may be disposed on various inclined positions, as indicated in dotted lines at 23, when desired. These parts of the clamp may be of forms commonly used in devices of this class, though the parts may be made in other preferred forms as occasion may require.

On the free end of the arm 12 of the spanning frame 10 is a second jaw member 24 having a fiat head or plate 25, and project-- ing from the underside of this plate are two spaced lugs 26, 27 These lugs are disposed in straddle arrangement on the free end part of the arm 12 of the frame 10 so that the upper face of the flat head 25 is in opposed relation to the exposed face ofthe flat head 21 of the adjustable jaw member 20, and the lugs 26, 27 of the jaw member 2 1 are pivoted, at 28, to the arm 12 of the frame 10. The aw member 25 may thereby be adjusted to inclined positions, as indicated in dotted lines at 29, to and from a normal position in direct spaced opposition to the head 21 of the jaw member 20. Thus articles having surfaces disposed on different relative inclined planes may be securely clamped between the jaw members by adjusting these members accordingly.

When the heel 15, particularly of the form issaiaz' shown, is mounted on the upper 14 of the shoe, in the upper is fitted a last, as 30, and the tread end of the heel is usually on a difterent plane from the plane of the upper end of the last. The upper, last and heel of the shoe are arranged between the jaw members 20, 24, and with the clamping of these parts by screwing the stem or bolt 18 the jaw members will tightly engage the tread end of the heel and the upper end of the last. as shown in Fig. 1, with the jaw members being adjusted to conform with the positions of the engaged surfaces of the heel and last without requiring the use of wedges as is incident to the present methods in use for mounting the heels on uppers of shoes.

\Vhile in the foregoing description, I have embodied the preferred form of my invention. I do not wish to be understood as limiting myself thereto, as I amaware that modifications may be made therein without departing from the principle of sacrificing any of the advantages of this invention, therefore. I reserve to myself the right to make such changes as tairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1'. In a clamp of the class characterized, the combination with aspanning frame, of a jaw member with a flat head having protruding from one of its faces two spaced lugs straddling and pivoted on one end of the frame for being adjusted to inclined positions relative to the other end of the frame.

2. In a clamp of the class chm-acterized. the combination o1 a substantially ll-shrped spanning frame having on one of its ends adjustable supporting" means with means for adjusting the supporting means toward and from the other end of the frame, and a jaw member with a flat head having two spaced lugs straddling); and pivoted to the other end of the frame whereby the head may be adjusted to inclined positions from a normal position in opposedrelation to said supporting means.

This specification signed and this 16th day of March A. D. 1923.
